What’s the best example from Westeros history of Starks and Targaryens working together to defeat a common enemy? The TV show has Jon Snow talking about this in a trailer, but I can’t think of a good specific example.

Well, the Starks were active during the Dance of the Dragons, Rickard Stark fought in the War of Ninepenny Kings, and Rickon Stark fought and died by the side of Daeron I during his “Conquest,” but it strikes me as a line that’s written more to sound good than to make sense.
